1. Vauxhall Astra 1.6 CDTi 110 Ecoflex

Official combined mpg 83.1 True mpg 56.3 % difference 32.2%

This version of the Vauxhall Astra is the most efficient family car we've ever tested, averaging an impressive 46.4mpg in town and more than 73mpg on rural roads. This 1.6-litre diesel engine is our pick of the range for company car drivers, with a CO2 figure of 97g/km. It's brisk, too, taking just over 10 seconds to get to 60mph, and it is also very refined. If you're looking for a comfortable and economical family hatchback, look no further.
